SLIDE BUCKLE Filed Sept. 26, 1931 INV; "FmF-1 JEH-1N H. DEMKEE Patented Jan. 17, 1933 Pa'rleN'r.V OFFICE JOHN H. DOMKEE, or WEST navEN, coNNEoTIcUn'AssIGNoR To THE WIR-E NOVELTY CONNECTICUT applicannima september aaien. serial Nb. seneca/ This invention relates to slide buckles used for adjusting the length of looped straps, webbing and the like, without penetrating the material, the invention, vwhile adapted `to any bent wire form of slide buckle, is especially adapted to that class oitslideV buckles lnade of' round wire bent to forni a pair of loops connected at oneside and free yat the opposite sides and having intermediate barstructure portions integrally extending from the free side of the loops to the connected side thereof. f The objects of the invention are to'provide a reversible slide buckle Yhaving the strapgripping upper and lower bars flattened in the plane of the slide buckle and otherbars having spaced projectionsextending along` said plane; to provide a slide buckle of the pair of loops type of which the upper and lower horizontalbars areiiattened in the plane of the loops, and the intermediate bar-structure is provided with spaced projections eX- tending in opposite directions Aalong said plane 5 to provide means for securing together'.

the free sides of such a pair of loops; and to provide means for securing the wire ends of the intermediate bar-structure portions to the connected side of the loops. Vith these and other objects in view as may become apparent from the within disclosures, the invention' consists not only of the particular form herein pointed out and illustrated in the drawing, Vbut readily admits of certain modifications within the scope of what hereinafter may be claimed. While the character of the invention is broad in its application to the art, reference is here made to one illustrativel device embodying the invention and illustrated bv the accompanying drawing in which the Figure 1 is an upright elevation of the device; the Figure 2 is a cross-section on the line 2'-2 of the previous ligure; and theV Fig- Y ure 3 is a cross-section on the lineV 3-8 '50 issued to your petitioner Juneflb, 1931, and

MANUFACTURING GOM'VPANY, OF HAVEN, :CONNECTICUT, A CORPORATION 0F 'Y l SLIDE BUCKLE J une 10, 1930, respectively, on slide buckles of which the intermediate bar-structures are provided with angular formations projecting in planes perpendicularto, and out of,

the plane" of the buckle. Referring more particularly to the drawing, however, the

slide buckle as illustrated is provided with projections formed, vnotby bending the wire but by pressing spaced portions of the wire to form nubs projecting therefrom and the upper and lower bar-structures are flattened in the plane of the slide buckle. f The device isk preferably madeL from a singlefpi'ece of round wire ofwhich a middle portion provides ithe integrally connected side,l of Aa pair of loops 2 and 3 lying in a common plane and iormedbyy bending bothwire end portions in substantially parallel relation to'provide the upper 4and lower horizontal barstructures 4: and 5',.respectively, ofthe pair of loops 2an`d 3, both wire end portions again being bent, butfinwardly toward one another, to'` provide the, relativelyV free sides '6" and 7 of the'pair'of loops2 and 3, and vboth .wire en'id portions again being bent inwardly `an 'dsub s'tantially parallel with the upper'and lower horizontal bar-structures 45 and 5 to leave the freesides yand "7 in substantially relativev engagement and'A toA providelthe vintermediate bar-structure portionsSandQ separating the" ties lOandjll, respectively, within they plane ofthe loops2 and 3, withthe'connected side bar 1. Y' At some convenient step in the forma- Vtionotthe slide buckle, asyaforesaid, the spaced nubs-12 are pressed out of the metal of the round wir-e intermediate,barstru'cture portion 8 so .that the nubs 12'v project thereV from along the said plaine ofthe loops 2 andy 3, and the spaced nubs 13,*are pressed out of the metal of the round wire intermediate barstructure'portion 9'so that the nubs 13` project therefrom alongsaidV plane in a direction op' posite to. that ofthe nubs 12, and the upper and lower vhorizontal rbfar-'structures i land v5 each having an inner edge'p'orti'on 14 lflat` tenedy in the said planeof `1theloops 2 and Toprevent accidental or A'wanton separation of the relatively engaging free sides 6 and 7 of the loops 2 and 3, the engaging metal surfaces at the free sides 6 and 7 are united, as at 15, in permanent intimate union, as by welding, brazing or soldering, so that the original character of said metal surfaces cannot be restored by any force effecting the mere separation of the loops 2 and 3 at that place, and the engagmg metal surfaces of the extremif 1o elevation opposite to that illustrated by the Figure 1 is substantially identical to the elevation thusillustrated. vWhile the relatively engaging metal surfaces of the loops 2 and 3 at their free sides 6 and 7, and the engaging metal surfaces ofthe extremities and 11 of theintermediatc bar-structurepor tions 8 and 9 and the connecting sido bar 1, are illustrated and described as preferably being united in permanent intimate union, these engaging parts of the device each may be relatively secured, if desired, in any loss permanent and intimate manner.

In, use, a strap 17 may be threaded into the slide buckle as illustrated bythe Figure 2. so that the flattened inner edges of the portion 1li of the upper and lower horizontal barstructures i and 5 andthe spaced nubs 12. and 18 extend in different directions into the path of the threaded strap 17 to grip the strap from different angles to prevent theslide buckle sliding upon a taut strap threaded therethrough. t

Themodified vform of the device, illustrated bythe Figurei, materially diers from the preferred structure only inthatthe nubs 12 and `13 are provided by an intermediate barstructure of the one portion 8 and the upper andy lower horizontal bar-structures Li and 5 are. flattened throughout, not only their entirek length but their entire width as well, but bothmodied and preferred forms of the device are similar in that theyy each provide gripping edges and nubs extending in different directionsl into the path of a strap threaded into the slide buckle, the modified form having engaging metal surfaces, as at 15 and 16united in permanent intimate union asin the preferred form of the device.

, I claim 1'. A slidebuckle comprising a piece of Wire of uniform diameter throughout it-sy length and bent to form a substantially reetangular frame having side,y upper, lower and vintermediate bar-structures, the upper and lower bar-structures being flattened in the' plane of the frame andthe intermedia-te barstructure being provided with spaced nubs,

`each nub being pressed out4 from said uniform diameter to extend beyond they bar-structure of `which a full diameter is maintained between, and at the rear of, said nubs, said nubs extending in opposite directions along said plane and cooperating with the inner edges 0f the iattened bar-structures to grip a strap threaded into the slide buckle.

2. A slide buckle comprising a piece of wire Vofrvuniform diameter throughout its` length said uniform diameter Vto ext-end beyond said portions ofv which a full diameter is maintained between, and at therear of said nubs,v said nubs extending along said plane in opposite directions and cooperating with the inner edges of the liattened bar-structures to grip a strap threaded into the slide buckle, means uniting in permanent intimate union the engaging metal surfaces of the freeV sides of the loops, and means likewise uniting theengag ing metal surfaces of the extremities with thel metal surface of the-integrally connected side of the loops.
